摘　　要：内蒙古阿右旗陶来、努尔盖、红沙沟、赛因乌苏等四幅图戈壁半风成沙及大沙面积479km2,覆盖厚度一般为2～7m,较富含有磁铁矿细屑,粒度小于0.14mm,通过采集样品分析,估算Fe储量为1071431.2t。用一定强度的磁选就可吸附回收。The area of semi-aeollan sand and sand is 479 km2in Alxa Right Banner Taolai Gobi, Nu＇ ergai Gobi, Hongshagou Gobi and Saiyin Wusu Gobi in Inter Mongolia. The depth of sand covering is 2 to 7 meters, which contains rich magnetite crumble. The particle size of sand is less than 0.14 mm. Through the analysis of samples collected, estimate the deposit of Fe is 1 071 431.2 t, which can be recycled by intensity magnet.
